Speaker cable length for mono blocks

I have a very similar setup, with Aleph 3's and Quad ESL 63's. I tried it first with 8' Stealth Ultimate Ribbons and then with 18" lengths of the same cable. My experience: it is VERY MUCH WORTHWHILE to go for the shorter length! The 18" cables brought me MUCH closer to the music. I thought it was very good before, and maybe it was by any reasonable standard. But this was one more reminder of the audiophile mantra, "It can always get better."

The shorter the better. I have about one metre of what I think is Ultra Cable, which was highly regarded cable ten, twelve years ago. I have never felt the need to improve on this. One of the advantages of mono blocks, I think, is that you are able to position them close to the speaker. The idea is to keep the amps clear of the speakers so they don't interfere with dispersion (limits this to the sides with dipoles unless the amp is kept on the floor below the transducer element itself) and air circulation, and to keep the interconnects short also. No point in having long runs of interconnect to compensate for extra short speaker cables, unless they are balanced. On the subject of cabling, it is interesting to read what the Bryston site has to say before going off the deep end cable-wise. Interconnects and speaker cables are a fools paradise, so beware.

The shorter the better less resantace. The other point is you can get a much better cable.
